Amphibians typically have a larval stage that lives in water but there are many different behavioural adaptations that have developed among species to bypass this necessity.

Amphibians also use their skin for respiration and some small terrestrial salamanders rely entirely on this and have no lungs.

Amphibians have a skeletal system that is structurally homologous to other tetrapods, though with a number of variations.

Amphibians have a juvenile stage and an adult stage and the circulatory systems of the two are distinct.

Amphibians have two kidneys located dorsally, near the roof of the body cavity.

Amphibians have soft bodies and thin skins, lack claws, defensive armour or spines and seem relatively helpless.

Amphibians and reptiles have no ovarian medulla ; the central part of the ovary is a hollow, lymph-filled space.

Amphibians have a three-chambered heart.

Amphibians must return to water to lay eggs, in contrast, reptiles-whose amniote eggs have a membrane ensuring gas exchange out of water and can therefore be laid on land-were better adapted to the new conditions.

Amphibians and reptiles may have many cornua, while mammals ( including humans ) have two pairs, and birds only one.

Amphibians like toads and frogs have been featured also, and are depicted as lower creatures that live in more basic tribal systems and usually serve not as the primary villains but as secondary distractions to heroes.

Amphibians have an additional (" M ") type of ferritin ; the single ferritin of plants and bacteria most closely resembles the vertebrate H-type.

Amphibians in Costa Rica have acquired many adaptations for survival.

Amphibians have been well documented in páramo ecosystems, including the salamander ( Bolitoglossa spp.

Certain titles have been discontinued ( such as the Amphibians of North America and Families of Birds books ).

Amphibians possess a pancreas, liver and gall bladder.

Amphibians are members of the class Amphibia, whose living forms include frogs, toads, salamanders, newts and caecilians.

Amphibians are cold blooded vertebrates.

Amphibians: Frogs are the most crucial amphibian species in wetland systems.

The first two books are repackaged in one volume, and Adrian Mole: The Lost Years includes The True Confessions and The Wilderness Years, as well as a bonus not available separately, " Adrian Mole and the Small Amphibians ".

Amphibians and reptiles are rarely preyed upon.

Amphibians such as frogs are well represented in moorlands.

According to The Illustrated Encyclopedia of North American Reptiles and Amphibians, Mudkip and its evolutions are based on salamanders.

Amongst other vertebrates found in the National Park are fishes including Channa striatus, Channa punctatus, Cyprinus carpio, Wallago attu and Puntius sophore ( Pool barb ), Amphibians and Reptiles including Keel back Tortoise, Viper, Krait, Cobra, Water cobra, krait ( banded ) Bungarus fasciatus, Asian rat snake ( Beauty rat snake ), python, Russel's viper ( Daboia ), checkered garter snake and Common Lizard ( Viviparous Lizard ).

Amphibians and reptiles are mostly frogs, toads and lizards.

Ichthyophis, sometimes called the Asian caecilians are a genus of caecilians ( Limbless Amphibians ) found in Southeast Asia, southern Philippines, and western Indo-Australian Archipelago.

Amphibians in particular are able to take refuge in water or very wet mud.

Amphibians such as the Columbia spotted frog, tiger salamander and the boreal toad are relatively common.

After the dissolution of Strategic Investments, a few of the players took their winnings and split off into two independent groups, the Amphibians who were primarily led by Semyon Dukach and the Reptiles who were led by Mike Aponte, Manlio Lopez and Wes Atamian.

Amphibians evolved adaptations that allowed them to stay out of the water for longer periods.

Amphibians breathe by means of a pump action in which air is first drawn into the buccopharyngeal region through the nostrils.

Amphibians often eat the sloughed skin.

Amphibians swallow their prey whole, with some chewing done in the oral cavities of some species, so they possess voluminous stomachs.

Amphibians usually swallow food whole but may chew it lightly first in order to subdue it.

Amphibians also retain the fifth connecting vessel, so that the aorta has two parallel arches.

Amphibians, reptiles, and birds use the same orifice for excreting liquid and solid wastes, and for copulation and egg-laying ; this orifice is known as the cloaca.

Amphibians were the dominant land vertebrates, of which one branch would eventually evolve into reptiles, the first fully terrestrial vertebrates.

Amphibians include the green toad, American toad, common tree frog, and the Cretan marsh frog.

Amphibians were diverse and common ; some were several meters long as adults.

Amphibians were the dominant tetrapods until the mid-Carboniferous, when climate change greatly reduced their diversity.

Amphibians originally thrived in the marshes, sloughs, side-channels and oxbow cutoffs because of their warmer water, abundance of vegetation and nutrients, lower population of predators, and slower current.

** The first known underwater diving club in Britain, " The Amphibians Club ", is formed in Aberdeen by Ivor Howitt ( who modified an old civilian gas mask ) and some friends.
